Tendência da Temperatura e Precipitação na Península Antártica

Abstract

The Antarctic Peninsula has experienced increasing in air temperature which is higher than the global average. Thus, monthly trends in extreme air temperature and precipitation data in the Antarctic Peninsula are evaluate. Monthly averaged minimum and maximum air temperature and precipitation from 1969 to 2010. Have been analyzed by the Mann-Kendall and Student’s t- tests to identify the slope of the linear regression, adopting 5% of significance level for both tests. The results indicate an increase of both temperatures analyzed, with a larger trend for the minimum air temperature in particular in autumn and winter season. Precipitation showed a decrease trend in almost every months.
